Answer 1

Answer:

The best value is $\ 180$ for $15$ calendars.

Step-by-step explanation:

Lets find out the unit cost of each calendars with different prices given here.

• The price of $6$ calendars is $\ 114$.

Unit cost of these calendars $= \frac{114}{6} = \ 19$

• The price of $8$ calendars is $\ 144$.

Unit cost of these calendars $= \frac{144}{8} = \ 18$.

• The price of $10$ calendars is $\ 160$.

Unit cost of these calendars $= \frac{160}{10} = \ 16$.

• The price of $15$ calendars is $\ 180$.

Unit cost of these calendars $= \frac{180}{15} = \ 12$.

• The price of $20$ calendars is $\ 300$.

Unit cost of these calendars $= \frac{300}{20} = \ 15$.

So the best value from customer point of view is the lowest unit cost.

And the lowest cost is being offered for $15$ calendars $\ @\ 12$ per calendar.
